Filter and Search

Last updated: 12 January 2020

Trend Micro Cloud One™ – Conformity offers a variety of filters when viewing rules and checks on available reporting tools. The filtered results can be viewed by Rule, Resource, or Standards or Frameworks.

Using the filter, you can take several actions such as configuring each rule according to your requirements, resolving failures, viewing only suppressed or unsuppressed checks, Resource id, message, only show checks, generating a report.

Resource Id syntax

Regular expression syntax

A regular expression is a way to match patterns in data using placeholder characters, called operators.

Conformity browsers All checks uses Apache Lucene’s regular expression engine to parse these queries.

Reserved characters

Lucene’s regular expression engine supports all Unicode characters. However, the following characters are reserved as operators:

. ? + * { } [ ] ( ) “ \

To use one of these characters literally, escape it with a preceding backslash or surround it with double-quotes. For example:

\@ # renders as a literal ‘@’

\\ # renders as a literal ‘\’

“john@smith.com” # renders as ‘john@smith.com

Anchor operators, such as ^ (beginning of line) or $ (end of line) are not supported. To match a term, the regular expression must match the entire string.

Standard operators

Lucene’s regular expression engine does not use the Perl Compatible Regular Expressions (PCRE) library, but it does support the following standard operators.

.

Matches any character. For example:

ab. # matches ‘aba’, ‘abb’, ‘abz’, etc.

?

Repeat the preceding character zero or one times. Often used to make the preceding character optional. For example:

abc? # matches ‘ab’ and ‘abc’

+

Repeat the preceding character one or more times. For example:

ab+ # matches ‘ab’, ‘abb’, ‘abbb’, etc.

*

Repeat the preceding character zero or more times. For example:

ab* # matches ‘a’, ‘ab’, ‘abb’, ‘abbb’, etc.

{}

Minimum and maximum number of times the preceding character can repeat. For example:

a{2} # matches ‘aa’

a{2,4} # matches ‘aa’, ‘aaa’, and ‘aaaa’

a{2,} # matches ‘a` repeated two or more times

** **

OR operator. The match will succeed if the longest pattern on either the left side OR the right side matches. For example:

abc xyz # matches ‘abc’ and ‘xyz’

( … )

Forms a group. You can use a group to treat part of the expression as a single character. For example:

abc(def)? # matches ‘abc’ and ‘abcdef’ but not ‘abcd’

[ … ]

Match one of the characters in the brackets. For example:

[abc] # matches ‘a’, ‘b’, ‘c’

Inside the brackets, - indicates a range unless - is the first character or escaped. For example:

[a-c] # matches ‘a’, ‘b’, or ‘c’

[-abc] # ‘-‘ is first character. Matches ‘-‘, ‘a’, ‘b’, or ‘c’

[abc\-] # Escapes ‘-‘. Matches ‘a’, ‘b’, ‘c’, or ‘-‘

A ^ before a character in the brackets negates the character or range. For example:

[^abc] # matches any character except ‘a’, ‘b’, or ‘c’

[^a-c] # matches any character except ‘a’, ‘b’, or ‘c’

[^-abc] # matches any character except ‘-‘, ‘a’, ‘b’, or ‘c’

[^abc\-] # matches any character except ‘a’, ‘b’, ‘c’, or ‘-‘

Wildcard syntax

Wildcard syntax supports two wildcard operators:

  • ?, which matches any single character
  • *, which can match zero or more characters, including an empty one

    Example:
    “sg-*” // finds all resources starting with “sg” and ending with any number of characters
    “sg-?s” // finds all resources starting with “sg” and ending with any one character+ the letter “s”

Only show checks

Only show checks

The Older than and Newer than range enables you to view all checks generated for a selected number of days in the past.

  • Older than X days ago: select a value to display all checks older than (before) the entered number of days from today.
  • Newer than X days ago: select a value to display all checks newer than (after) the required number of days up to today.
  • Older than X days ago AND Newer than X days ago: Enter values for both Older than and Newer than to display checks for the required date range i.e from the newer than to the older than date.

How it works

The filter converts the values entered in Older than and Newer than fields to the date of check creation and assigned a status, or the change of status from “Success” to “Failure”, or from “Failure” to “Success”.


For example:

Today is the 10th November.

  • If you enter “2” for Older than days ago, then

The date calculated = 2 days from today = Nov 8. And you can view all checks that are older than (before) November 8.

  • If you enter “3” for Newer than days ago, then

The date calculated = 3 days from today = Nov 7. Only checks newer than (after)7 November upto today will display.

  • If you enter values in both the fields i.e. 2 for Older than AND 3 for Newer than, then the date range to display checks will be from 7th -8th November.

Note: The availability of options on filter depends on the functionality that you are accessing.
